ERC Warning Symbol modified in library, about GND,+3V3 and +5V

[retiredfeline]

See this post about the same problem happening to someone else:

Warning: Symbol 'GND' has been modified in library 'power'

I’m pretty new to kicad. ERC complains about GND and +5V symbols. I tried to ‘update symbol from library’ and remove and add the symbols again but with no luck. kicad 6.0.10 [obraz]
